2 Supplement 1 International Versions of the Background Questionnaires Population 1 Overview This supplement contains the international versions of the Population 1 background questionnaires in the following three sections: Section 1: Section 2: Section 3: Student Background Questionnaire (SQ1) Teacher Background Questionnaire (TQ1) School Background Questionnaire (SCQ1) Tables S1.1, S1.2, and S1.3 list all of the international background variables corresponding to each of the student, teacher, and school background questionnaire items. The international versions of the questionnaires were designed to provide an opportunity for individual countries to make modifications to some questions or response options in order include the appropriate wording or options most consistent with their own national systems. In the international versions of the questionnaires, such questions contain instructions to NRCs to substitute the appropriate wording for their country and/or to modify or delete any inappropriate questions or options. These instructions were indicated in two ways in the questionnaires: 1) NRC NOTE: 2) <International Option> (indicating that the NRC was to substitute, if necessary, an appropriate national option that would retain the same basic interpretation as the international version) Documentation of any national adaptations of the student, teacher, and school background questionnaire items is included in Supplement 3 to provide the user with information required to evaluate the availability of internationally-comparable data for use in secondary analyses involving the TIMSS contextual variables.
